Sierra Marine Exhaust Manifold Gaskets

4.33 out of 5 stars 3 Customer Reviews

Sierra Marine exhaust manifold gaskets are engineered to meet or exceed manufacturer specifications—and provide added value to boaters and marine mechanics. Exhaust manifolds take a beating in the watercraft environment and require regular inspection to avoid catastrophic engine failure. After an inspection (or replacement), it's equally important to replace the gaskets. Sierra Marine offers gaskets in a variety of configurations for direct-fitment on most popular engine make applications. Sierra Marine exhaust manifold gaskets are designed to perfectly match the exhaust ports for your engine.
